The capacitive touch screen is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are coated with one layer of ITO, and the outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working face, and four electrodes are introduced at four corners.The distinction between good and bad screens is, in fact, all that matters is how consumers feel.The first is whether the response is sensitive, accurate and stable.You can start this up and try it out;Secondly, whether it is durable, whether the surface is easy to scratch, whether it is easy to keep fingerprints, whether there are water ripples after pressing, whether it is easy to deform;Finally, some bonus points are whether the light transmittance is high, whether it reflects light, whether it is resistant to fall.Whether it's waterproof, etc.
